None
func None(notExpectedValues ...any) TestDeep
None operator compares data against several not expected
values. During a match, none of them have to match to succeed.
td.Cmp(t, 12, td.None(8, 10, 14)) // succeeds
td.Cmp(t, 12, td.None(8, 10, 12, 14)) // fails
Note Flatten function can be used to group or reuse some values or
operators and so avoid boring and inefficient copies:
prime := td.Flatten([]int{1, 2, 3, 5, 7, 11, 13})
even := td.Flatten([]int{2, 4, 6, 8, 10, 12, 14})
td.Cmp(t, 9, td.None(prime, even)) // succeeds

Example
Base example
t := &testing.T{}
got := 18
ok := td.Cmp(t, got, td.None(0, 10, 20, 30, td.Between(100, 199)),
"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
fmt.Println(ok)
got = 20
ok = td.Cmp(t, got, td.None(0, 10, 20, 30, td.Between(100, 199)),
"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
fmt.Println(ok)
got = 142
ok = td.Cmp(t, got, td.None(0, 10, 20, 30, td.Between(100, 199)),
"checks %v is non-null, and ≠ 10, 20 & 30, and not in [100-199]", got)
fmt.Println(ok)
prime := td.Flatten([]int{1, 2, 3, 5, 7, 11, 13})
even := td.Flatten([]int{2, 4, 6, 8, 10, 12, 14})
for _, got := range [...]int{9, 3, 8, 15} {
ok = td.Cmp(t, got, td.None(prime, even, td.Gt(14)),
"checks %v is not prime number, nor an even number and not > 14")
fmt.Printf("%d → %t\n", got, ok)
}
// Output:
// true
// false
// false
// 9 → true
// 3 → false
// 8 → false
// 15 → false
CmpNone shortcut
func CmpNone(t TestingT, got any, notExpectedValues []any, args ...any) bool
CmpNone is a shortcut for:
td.Cmp(t, got, td.None(notExpectedValues...), args...)
See above for details.
Returns true if the test is OK, false if it fails.
If t is a *T then its Config field is inherited.
args… are optional and allow to name the test. This name is
used in case of failure to qualify the test. If len(args) > 1 and
the first item of args is a string and contains a ‘%’ rune then
fmt.Fprintf is used to compose the name, else args are passed to
fmt.Fprint. Do not forget it is the name of the test, not the
reason of a potential failure.
See also CmpNone godoc.
